Grey Matter's small size belies his great calculative and technical intellect. He can create extremely advanced machinery from spare parts, understand the function of any device at a glance, and make sophisticated repairs to complex machines (such as a warp-drive engine).<ref name="Rad">''[[Rad]]''</ref> In fact, when [[Ben Tennyson (Classic)|Ben]] becomes Grey Matter, he instantly knows more about the [[Omnitrix]]'s inner workings, including its malfunctions;<ref name="ASP">''[[A Small Problem]]''</ref> how to rectify it being tampered with; and how to remove its limiter (the latter two being demonstrated by [[Ben Tennyson (Dimension 23)|Ben 23]] as [[Brainfrog]]<ref>''[[It's a Mad, Mad, Mad Ben World: Part 2]]''</ref> and [[Ken Tennyson (Original)|Ken]] as Grey Matter<ref name = "Ken 10">''[[Ken 10]]''</ref>, respectively.)
   
Grey Matter's intellect serves as a problem solver and analytical help in difficult situations. This allows Grey Matter to think more strategically when brute force is inefficient. In fact, Grey Matter is smart enough to know how to unlock the [[Omnitrix (Original)|original Omnitrix]]'s [[Master Control]], something only [[Ken Tennyson|Ken]] has demonstrated.<ref>''[[Ken 10]]''</ref>

Grey Matter's intellect serves as a problem solver and analytical help in difficult situations. This allows Grey Matter to think more strategically when brute force is inefficient. He is also generally knowledgeable; even if he does not know something, he can learn it very quickly.{{Refn|[[:File:Grey Matter Can Learn Things Quickly.PNG]]|group = DJW}}

Grey Matter's size allows him to squeeze into small spaces and he can climb walls due to microscopic pads on his skin.{{Refn|[[:File:Grey Matter Wall.PNG]]|group = pop-up}}<ref name="SOTO"/> He also has sharp teeth that can cause massive pain to those he bites.<ref name="ASP" />
Grey Matter can sometimes manipulate living things by stimulating certain parts of their nervous system if such beings can be controlled by external stimuli.

Grey Matter is stronger than he looks, as he was strong enough to move a cleaner's bucket with mops in it<ref name="Ultimate Weapon">''[[Ultimate Weapon]]''</ref> and break a coolant pipe to freeze the [[Vreedle Brothers]].<ref>''[[So Long, and Thanks for All the Smoothies]]''</ref>

Grey Matter can breathe underwater<ref>''[[They Lurk Below]]''</ref> due to having gills, making him amphibious.{{Refn|[[:File:Galvan Amphibious.PNG]]|group = DJW}}
Grey Matter was the weakest alien in the original series due to his miniscule size, but he compensates with his intellect and efficient technological and calcuative skills.

[[File:Problem (141).png|thumb|218x218px|Small Size]]

How do I stop this thing? I'm a thinker, not a fighter! Think...think...

– Grey Matter, thinking of a way to subdue Tyrannopede.[5]

Grey Matter is the Omnitrix's DNA sample of a Galvan[6][4] from the planet Galvan Prime.[merch 1]

Appearance

Ben as Grey Matter

Grey Matter is a grey-skinned, frog-like, bipedal alien that is only six inches tall[7][1] with large green eyes, which have rectangular pupils and horizontal eyelids.

In the Original Series, Grey Matter wore a white jumpsuit with a thin vertical black stripe down the front, his eyes were yellowish-green, his forehead had a larger version of the jumpsuit's stripe, and the original Omnitrix symbol was on his back.

In Ultimate Alien, Grey Matter looked exactly the same as before, except his skin was slightly lighter, his eyes were green and he wore the Ultimatrix symbol on his chest.

In Omniverse, Grey Matter now has a green jumpsuit with a black belt. His suit collar is now black, and the stripe on his head and jumpsuit are no longer present. He wears black, fingerless gloves with a green rectangle on the back. His neck is slightly longer, and his Omnitrix symbol has returned to his back.

11-year-old Grey Matter in Omniverse looks exactly the same as he did in the Original Series except his collar is black, his eyes are green, and his skin tone is slightly different.

Gwen as Grey Matter

Gwen as Grey Matter had Gwen's hair and more oval-shaped eyes, with much smaller pupils. She wore a light blue jumpsuit with dark blue sleeves, and the Omnitrix symbol was on her back. She lacked the stripes Ben's Grey Matter has.

Ken as Grey Matter

Ken's Grey Matter looked the same as 10-year-old Grey Matter in the Original Series.

Powers and Abilities

"Let's kick a few butts!"
"Actually, most of the Galvan species are known as technological geniuses."
"Oh. Then let's outthink a few butts!"

No Watch Ben as Grey Matter and Professor Paradox.[8]

Grey Matter's small size belies his great calculative and technical intellect. He can create extremely advanced machinery from spare parts, understand the function of any device at a glance, and make sophisticated repairs to complex machines (such as a warp-drive engine).[9] In fact, when Ben becomes Grey Matter, he instantly knows more about the Omnitrix's inner workings, including its malfunctions;[1] how to rectify it being tampered with; and how to remove its limiter (the latter two being demonstrated by Ben 23 as Brainfrog[10] and Ken as Grey Matter[11], respectively.)

Grey Matter's intellect serves as a problem solver and analytical help in difficult situations. This allows Grey Matter to think more strategically when brute force is inefficient. He is also generally knowledgeable; even if he does not know something, he can learn it very quickly.[DJW 1]

Grey Matter's brain capacity makes Ben smarter about things he has never even seen before, like Kraab's alien circuitry.[pop-up 1][12] Grey Matter's multidisciplinary intellect can also extend to understanding certain languages, such as that of the Lovely Duck's Artifical Intelligence, Pyxi.

Grey Matter's size allows him to squeeze into small spaces and he can climb walls due to microscopic pads on his skin.[pop-up 2][4] He also has sharp teeth that can cause massive pain to those he bites.[1]

Grey Matter is stronger than he looks, as he was strong enough to move a cleaner's bucket with mops in it[13] and break a coolant pipe to freeze the Vreedle Brothers.[14]

Grey Matter can breathe underwater[15] due to having gills, making him amphibious.[DJW 2]

Grey Matter has a long prehensile tongue, owing to his insectivore nature, as demonstrated with Blukic.[16] As a Galvan, he also possesses a 'pre-brain' which deals with all basic bodily functions.[17][18]

Weaknesses

Problem (141)

Small Size

Grey Matter's small size makes him unsuitable for physical battle, so he must outsmart his enemies in a fight. Animals like dogs and cats can be a problem, as they may see Grey Matter as a chew toy or food to them.[13]

Grey Matter does not know everything, as seen when he (initially) did not know which galaxy his species is from.[1] Despite possessing immense intelligence, Grey Matter can still make miscalculations, as his attempt to upgrade the Rust Bucket's air conditioner caused it to overheat instead, incapacitating the vehicle.[19]

Being a Galvan, Grey Matter is at a massive disadvantage against the Nemetrix's sample of a Omnivoracious due to his small size.[20]

Grey Matter is vulnerable to electricity.[21]
